Mechanical Analysis on Secondary Lining Damaged by Local Load under Earthquake

Abstract:

Article Preview

Secondary lining of Longxi mountain tunnel damaged seriously during Wenchuan earthquake. To interpret the seismic failure reasons about secondary lining, the analysis adopts mechanical calculation and numerical simulation method. As a result, it was found that the bearing condition of secondary lining has an obvious spatial effect when the local loads act on the tunnel. Due to the inertial force of local load exerted by vertical seismic action, the secondary lining tends to be cracking, spalling, or even collapse.
